Abstract

In order to manufacture a fiber by drawing a preform, said preform is made by collapsing a thick-walled silica tube having a reduced pressure established therein and heated in successive passes. The tube is prevented from ovalizing by beginning each pass with a portion bearing against a coaxial internal conical guide. The invention is applicable to low cost fiber manufacture.
